IDUSTLESS ASH REMO'VER.

Application inea July A2, 192e. serial No. 120,237.

This invention relates to certain new and useful improvements in ash removers, and has more particular reference to an improved device for facilitating removal of ashesvfrom a stoves and furnaceswithoutdanger of spilling the ashes upon the floor or liberating dust.

The primary object ofthe present invention is to provide an ash remover of the lo above kind which `is extremely simplev and Y durable in construction as well as eiiicientin operation, and whichmay be readily placed into practical use.

A further object is to provide an ash remover of the above, kindembodying an ashv pan ory ash receiving and discharging unit adapted tok be readily: placed within the ash pity of stoves and furnaces so that the ash pit door may be closed when-removal of the ashes is not taking place and an outlet or discharge tube adapted for removable association with the outlet of the ash receiving and discharging unit and having an ash can lid or cover rigidly attached to the under-l side thereof, whereby the ashes mayl beconveyed from the ash receiving and discharging unit to the ash can without'fdanger of spilling the ashes upon the floor or liberating dust. y i

A still further'object is to provide an ash receiving and discharging unit embodying a screw or spiral conveyor for eecting dis charge of theashes, and anfoperatingshaft carried bythe delivery or discharge tube, in combination with means to .automatically operatively connectthe operating shaft with the conveyor shaft when the delivery tube Cil is engaged with the outlet of the ash rev ceiving and discharging unit, whereby the conveyor may be actuated for removal of the ashes. f l Y Other objects will become apparent as the nature of the invention is better understood, and the same consists in the novel form, combination and arrangement of parts here-V v inafter more fully described, shown inthe accompanying drawings and claimed.

'In the drawings, wherein like reference characters indicate vcorresponding parts throughout the several views t Figure 1 is a top plan view of an ash'remover constructed inv accordance with:Y the present invention;

Figure 2 is a view thereofpartly in side elevation and partly in central longitudinal section; f

Figure 3 is a transverse vertical sectional view taken upon line 3 3 of Figure l;

Figure a is a bottom plan view of the delivery or discharge tube and the attached ash can lid, together with the associated conveyor actuating or operating shaft;

Figure 5 is a transverse vertical sectional View taken substantially upon line 5 5 of Figure 2;r

Figure 6 is an enlarged fragmentary perspective view illustrating the means for effecting clutching or operative connection between the adjacent ends of the actuating shaft and the conveyor shaft, and

vFigure 7 is a. view somewhat similar to Figure 2, with the conveyor slid partly from the hopper into the delivery tube to effect cleaning of ashes from the latter.

Referring more in detail to the drawings, the vpresent invention embodies a hopper 5 preferably constructed of sheetv metal and adapted to be inserted through the ash pit merge with a centrally and longitudinally disposed Y trough 7 forming the bottom of the hopper. This trough is closed at its rear end by the rear end wall of the hopper, but is open at its forward end in communication with a relatively short nipple or outlet pipe 8 rigid with and projecting outwardly from the outer end of the hopper as shown in Figure 2. The outlet nipple 8 will be positioned within the ash pit so that the usual ash pit door can be closed when the removal of the ashes is not taking place, and fitting in the trough .7 as well as suitably rotatably supported in the latter to extend from end to end of the same is a helical or spiral conthe outlet nipple 8, and closed' atxits` other end, a conventionalv ash can lid or cover 12, being fixed to the under side of the dis charge tube 11 and having an opening;J in thel top thereof in register with a bottom discharge opening provided in the deliverytub- 11 as generally indicated at 13. The openings at 13 in the ash can cover 12 and: the de livery tube 11 are extended as near as possible-to the open end of thetube 1=1 so that as the ashes are discharged 'from the outlet nipple-8 they will readily ind their Way through theV openings at 13 into the ash can. The dischargetube 11 has an actuating shaft 14` journaled-l axially therein and projecting be yond or through the outer end of the same wherel it is equipped with a suitable handlel or crank 15 for facilitating manual turning Means is provided toy antoupon engagement of the ,deli-very tube 1-1 with the outlet nipple 8, andy this means preferablyA embodies opposed angular armsv l6 rigid,A with the shaft 14- a-ndengageabl'e with a transversev pin 1-7 extending through the shaft 9.

Thefdischarge tube 111 is closed at theouter end oftheopening at 13 bymeans-'of a trans verse partition or bearing plate 18- in which the-shaft 14 is journaled.

Thehopper 5-and associated parts are'dis posed withinv the ash pit andtheash pity doorclosed under normali conditions. However,` when it is desired to remove aehes'I which` havey collected in the hopper 5'-, thetu ash'` pit door isfopenedfand thedelivery'tube 112 is fitted onto the outlet nipple 8, where upon the crank shaft 14 is turnedj inea clock'- wisey direction so asV to7 cause they arms 16i toengageithe pin 17 and thereby transmit the rotationl of shaft 14ey to the conveyor shaft". Upon rotation of the conveyor the` ashes` in` thehopper are discharged. from: the latter` and conveyedv to the ash,` can upon which the lidt or cover 12 is placed.. It willi thus: be

seen that the removal of the; ashes may. be*` electedfiromtimeito time asfound necessarywithout danger of; spilling the same upon'V thclloor or of: liberating v the dustin the room ory building inv which the stove=or furnace is-l positioncch When the hopper 5 has beeny fully emptied of the ashes, thedelivery tube 11,l is removed fromI the outlet nipple 8y and maybe` left uponthe-fash can or stored away when notin use. The ash pit door of the stove or furnace may then be conveniently closeduntilthe next'ash removing operation takes place;

Itl will be noted that the conveyor 9, 10,. when normally positioned as-v in Figures 1 and 2, terminates at itsf outer end within the` trough 7 andy a distance from the openings:

13in thev7 delivery tubell and coverl 12. InV

view of this; fact it is desirable to provide somemeans for finally cleaning-i out of the deliveryl tube 11, such ashes as may remain therein between the outer end of the conveyor and the openings 13 after the hopper f 5y has. beenl completely emptied. For this purpose, the conveyor is slidably mounted inthe trough 7y soias t0 be capable of being slid outwardly into the delivery tube 11 for scraping the remaining ashes from said delivery tube into the ash can through thel openings at 13. In carryingout this con-l struction ak supporting rod 191 is` supported:1 axially or centrally`r of the trough 7, and the shaft 9b is of' hollow form and'l rotatably and` slidably disposed on the rod 19, one end ot the rodl 119; being 'xed to' thnrear wall? ot' the hopper 5 ass indicated at 2() Further, the operatin `shaft 14' issli'dablel through the outer en l of the delivery tube lil and the bearin plate-18=so thatwhen the shaft 14'. is pul ed outwardly, the conveyor may beslid1 outwardly to the*I position indicated in Figure 7 by.` reason off' the nature of` they clutching means.v 16,l 17.', described above; This outwardl sliding of` the conveyor: natu rally resulte; in scraping ashes which remain in the tube lflL out otrthelatter fior ultimatell findingtheirvvay` into. theash. can throng 1 the openings at 13; In: usingy the presentap.- paratua:thisscl ing of'theashes fromn the delivery tube*r 111' 1s effected after the hopper 5 hasbeeni completely` emptied; but before the delivery tube 1214 isn disconnected from. the hopper,y andi the. conveyor is then: slid backv to its` normal! positionl ot Figurel 2 so that, the-` delivery'y tuba 1=1 may. be disconnected from the ho per without any danger of dust. or ashes falling out of they delivery tube 1l ontoi thet floor. As shown, the rod.k 19 isfA off 105 considerably smaller diameter than; thev shaft 9i and: lmssecuned thereto bearings21 and` 22A for rotatably and slidablyy supporting ther shaft' 9.
